We usually get some questions about how many hydrogen bonds these compounds can create, we use it to differentiate between the boiling point of each one of them so it would be great if you could help me.

So what I know that H2O has 4 hydrogen bonds those are 2 from hydrogen atoms and 2 from other molecules that has 2 hydrogen atoms connected to the 2 lone pair of electron that the oxygen has.

In HF, It has 2 hydrogen bonds. The same explanation implies here. In NH3, 2 hydrogen bonds because N doesn't have the required amount of lone pairs to make more hydrogen bonds.

The hydrogen bond is one of the strongest intermolecular attractions,

A single hydrogen atom can participate in two hydrogen bonds, rather than one. This type of bonding is called "bifurcated" (split in two or "two-forked"). It can exist, for instance, in complex natural or synthetic organic molecules
